My '95 has a head lamp control module that has started malfunctioning. Low beam is out but comes on if I trip the relay in the control module manually. Probably a blown transistor on the module but that is a rabbit hole.
I found some good advice on replacing it with a off-the shelf latching relay:

And then while rooting around in the junkyard for other things I found this beauty attached to a Saab 9000.

I yanked it out of the Saab and I'm going to try it out. It's pin compatible but not plug compatible so there's a little bit of jumper construction required. I'll let you know how it goes. My yard find was $6 and new they're listed at $24. For the win, that beats $200 for the Jaguar part.
